초록

The methionine-rich segments of the Fifty four homologue (Ffh) protein of Escherichia coli and its eukaryotic counterpart SRP54 are thought to bind signal sequences of secretory proteins. The structure of a chemically synthesized 25-residue-long peptide corresponding to one of the proposed methionine rich amphiphilic helices of Ffh was determined in water and in aqueous trifluroethanol (TFE) solution using CD ard NMR.
